If you’re thinking…

“There are so many things we could be doing, but what should we do right now?”
“Everyone has a different opinion on what’s slowing us down.”
“I’m too close to the data, I’m not sure what we are potentially missing here.”
“Growth isn’t as easy as it used to be.”
“What got us here isn’t working the same way anymore.”

Growth problems rarely announce themselves. The Growth Diagnostic shows you what’s really slowing momentum, which opportunities are worth acting on, and what to do first.

how it works

01
Growth Reset Call
Free · 45 minutes. A call with Zac to talk through where growth is stuck. You leave with fresh ideas on your growth and a clear answer on whether the Growth Diagnostic is right for you.
02
Kickoff Call
We sign a mutual NDA and MSA before work starts, then have a 60-minute deep dive with your founder or CEO and your growth or marketing lead to review your growth system: the plan, people, process, technology, and timing.
03
Diagnosis
Delivered over two weeks, once we have access and the Kickoff Call is done. We work from read-only access to your systems, with occasional targeted questions to one internal owner.
04
Growth Action Plan
You receive your Growth Action Plan: the top constraints, ranked opportunities, and what to do in the next 90 days. We review it together in a 90-minute meeting and align on next steps. If you don’t agree it holds at least $1 million in hidden growth opportunities, we refund the entire fee. If you hire us to help put it to work, the full fee is credited toward the 90-day engagement.
Example Growth Action Plan, a D2C subscription brand at a $28M run rate.

This is a simplified version. Your Growth Action Plan will have a long list of ranked opportunities with their own briefs. The best ones get turned into a 90-day, sequenced project plan. We can walk you through a full anonymized Growth Action Plan on your Growth Reset Call.

When they switched payment providers in March, the system went from chasing a declined card four times over two weeks to once over three days. They went from saving 31% of those customers to 6%. That is about 835 people a month who wanted to stay and left anyway. More than half of all cancellations are now people who never chose to cancel, and nobody on the team owns that number.

Frequency on the main prospecting audience is 4.2, up from 2.6 a year ago, and what it costs to reach them has climbed with it. 68% of last quarter’s spend went to four ads, all of them more than 5 months old. The symptom is content frequency, but the root cause is actually their testing process. For example, 12 outstanding tests last quarter weren’t even formally called.

New customers used to come back for a second order 44% of the time. Now it is 36%. It slipped a little every month for over a year, which is why nobody caught it. The dashboard shows one repeat rate for everybody, and that stayed flat, because subscribers kept ordering and hid what was happening to first-time buyers.

Nine percent of subscribers ship to a business address. They order 2.4 times the volume of a household subscriber and cancel at a third the rate. Put a workplace plan in front of the accounts already shipping to offices and watch the take rate.

The top six of a much longer ranked list, scored on impact, confidence and ease. Sequence is not the same as score: the retention fixes come first, because keeping more customers raises what you can afford to spend winning new ones.

Increasing spend, until failed payments have recovered for four weeks straight. The ad work raises output, not budget.

“Not to overstate it, Zac completely transformed The Pour Over’s growth strategy: we began feeding a quality/value signal back to Meta, shifted optimization toward higher-quality leads, doubled click rate in comparable cohorts, and increased spend by 30% while improving LTV to CAC in the process.”

Matt Whipple, Head of Growth, The Pour Over

“Zac & 4th Quarter helped us cut through the noise, identify which growth opportunities actually mattered, what was getting in the way, and where to focus next. That clarity played an integral role in growing from $10 million to more than $300 million invested on the Roots platform.”

“4th Quarter is Fieldcrest Ventures’ secret weapon. They audit growth assumptions before I invest and serve as the plug-and-play growth operating partner once I invest, de-risking my investments and improving returns.”

the secret sauce

01
This is a system “audit”, not a channel audit

The Growth Diagnostic starts at your Growth System: your plan, people, process, technology and timing. Then it drills into channels based on the constraints identified. You still get the channel-level analysis and optimizations, but you understand and have a plan for the root cause issues and the exponential opportunities that surface at the system level.

02
The Diagnostic is human-run and superpowered by AI

We built an AI harness that pulls your exports, maps the context, checks every claim against a second source, and flags numbers that are defined differently in different systems. It also helps surface insights and ideate, using what may be the world’s largest Growth library: 709 patterns across six libraries, including growth loops, up-to-date channel methodologies, and category creation stories. This enables us to leverage AI for what it’s uniquely qualified for, pattern recognition.

Meet your growth guide

Hi, I’m Zac Litwack. I’ve managed over $100 million in ad spend and built audiences into the billions of pageviews and streams. I helped grow OutKick and sell it to Fox in 2021, and most recently I ran growth at Roots, helping it go from $10 million to over $300 million invested on the platform.

Even after operating growth functions for over 15 years, I still have blind spots. This is especially evident when I’m running the same company for a few years. You test your original hypotheses. Some work. You build playbooks around them, and you get caught iterating on the same playbooks over and over again. You have trouble seeing the proverbial “forest from the trees” as you get closer and closer to the data and your users.

That is not a personal failing. It is what happens to every growth system as the company outgrows it.

What got you to $10 million usually won’t get you to $50 million or $100 million. These inflection points stress test your growth system, and if it doesn’t have a solid foundation you’re going to falter. That may be what you’re feeling right now.

I’ve missed things in my own business that someone from the outside would have caught.

That’s why we created the Growth Diagnostic: when you combine fresh perspective and Growth expertise, with AI tools purpose built for Diagnostics, in 2 weeks we can transform your growth.

You may be wondering

If we both think it’s a fit, we sign an MSA and a mutual NDA, and agree on access permissions with your IT team. The work begins once payment is received and the Kickoff Call and access are complete. You own the full diagnosis and the Growth Action Plan. If you want help putting the plan to work, 4th Quarter can stay on for a 90-day engagement, and your full Diagnostic fee is credited toward it.

Where your data goes, in order:

Exported data is downloaded to our local machine and used to produce the Growth Diagnostic and the resulting Growth Action Plan
The Growth Action Plan lives in Notion. We avoid storing raw client data there
We use AI tools, primarily Claude, to map context, analyze exports, synthesize data, find patterns across the libraries, and help produce the Growth Action Plan

Your data is not used to train public AI models. We also default to aggregated, anonymized, or redacted data wherever possible.

It depends on your growth model, but usually some mix of:

Website and content performance: GA4, Google Search Console, CMS analytics
Lead and CRM data: HubSpot, Salesforce, Pipedrive, Attio
Product behavior: Mixpanel, Amplitude, PostHog, Segment, internal dashboards
Email and lifecycle performance: Klaviyo, Customer.io, SendGrid, HubSpot, Mailchimp
Revenue and subscription data: Stripe, Maxio, Chargebee, Shopify, internal finance dashboards
Platform data: Meta, Google Ads, LinkedIn, TikTok, or wherever paid acquisition runs and wherever organic has real effort behind it
Sales call recordings or transcripts: Gong, Grain, Fathom, Chorus, Fireflies, or exported transcripts

We do not need raw PII by default. No names, no emails, no phone numbers.

The main caveat is recorded sales calls. They are often the most useful input we get, because they show buyer language, objections, urgency, and the gap between content awareness and purchase intent.

We know call recordings can carry sensitive customer and prospect information. We can handle them however your policy requires: redacted transcripts, selected excerpts, or AI-generated summaries.

Most of the work sits with us once access is granted. Your team’s commitment is concentrated at the start and the end. A typical engagement asks for:

Kickoff Call: 60 minutes with the founder or CEO, and the growth or marketing lead
Access setup: 30 to 90 minutes from an ops, data, IT, or marketing owner to grant read-only access or send exports
Follow-up questions: 1 to 2 hours total, async, usually to clarify metric definitions, customer segments, offer history, or gaps and inconsistencies in the data
Readout: 90 minutes with the team that will act on the Growth Action Plan
